PAPERI'FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 299,094-, dated May 20,1884. Application tiled May 19, 1883. (No model.)

To all whom it may concern.-

Be it known that l, JOHN l-I. STONEMETZ, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Conveying Devices forPaper-Folding Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being hadvto the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

This invention relates to a sheet-conveying mechanism for paper-foldingmachines, or to devices interposed between a printing-press andfolding-machine for conveying sheets of paper from the former to thelatter. Amechanism heretofore devised by me for this purpose consists ofa table or frame that is connected with the folding-machine, and hascarrier tapes or bands passing over rollers at the top of said table orframe and around rollers on the folding-machine, which serve to givemotion to said tapes. It has been found that these traveling tapes orbands frequently fail to perform their work, or do not worksatisfactorily, chiefly by reason of a want ofpropcr adhesion betweenthe tapes and the paper, thus causing the stoppage or retarded movementof the latter. In the present `invention I use all of the devices abovereferred to, and combine therewith milled or corrugated wheels or disks,which are tted on one of the upper guiderollers of the conveyer-tapes inproximity to the delivery end of the printing-press. The face speed ofthese milled or corrugated wheels or disks is faster than lthat oftheconveyertapes, so thatsai-d wheels will always propel or feed the paperalong and prevent it from stopping or being retarded in its movementwhile in transit between the press and folding devices.

In the drawings, Figure 1 is a side view of my improved sheet-conveyingattachment for paper-folding machines. Fig. 2 is atop view of the same.Fig. 3 is a detail sectional view of the milled feeding-wheel andsupportingbracket.

The letter A designates the delivery end of the frame of aprinting-press, and B indicates a paper-folding machine, having asheet-conveying attachment bridging the space between the same and thepress. rllhis attachment consists of an inclined board or table, C, thatis connected with the folding-machine frame by hinges, or otherwise. Atthe upper end of this board or table is arranged a horizontal transverseroller,D, and in juxtaposition thereto another roller, E. These tworollers are journaled in supporting-brackets F,which are secured at theupper end of the board or table C, as is shown in Figs. 2 and 3. Theup`per roller, D, lor the one nearest to the printingpress, has a seriesof milled or corrugated wheels, disks, or sections, G, which projectabove the tape-bearing surfaces of said roller, these surfaces beingformed by the smooth portions of the roller located between thecorrugated or milled disks G. The set of tapes H extend around theaforesaid roller l) and travel passed at the bottom around adriving-roller on the folding-machine. Another set of tapes, I, operatealtogether above theboard C, and are conducted around the roller Ethereof and a roller on the folding-machine. The tapes I run from apoint somewhat in advance of the tapes H, and thus a nip or spaceis leftbetween both sets of tapes, into which the paper the milled wheels ordisks G. It will be understood that the sheets coming from the presspass over the milled or corrugated disks or enlarged portions of theroller D, and as the face speed of said disks is greater than that ofthe follows th at if the tapes should fail to move the paper forward ina regular manner the milled disks will still perform their function ofmoving the paper forward at a regular and uniform rate of speed. Theclogging or retarded movement of the paper between the conveyertapes isin this manner, or by the use of the milled disks or corrugatedenlargements ofthe tape-roller, prevented by most simple and effectivemeans. rlhe projecting ridges of the milled disks catch the edge of theadvancing sheet and straighten it out, if itis not straight I-I and Iwithout any tendency to double back on itself.

I am aware that milled folding-rollers have from the printing-press isfed by the action of over and under the board or table C, beingconveyor-tapes operating between said disks it ICO and true7 so that itenters between the tapes v other tape-conveyer rolls of afolding-machine,

yet it is of special value at the place above described, where the sheetof paper is just passing from the printing to the folding machine. Afterthe sheet has fairly entered on its course through the folding-machineit is rarely checked or retarded.

Having thus described my invention, what I.

claim as new, and desire to secure by Letters Patent, is-

1. In a paper-folding machine, the combination, with a system ofconveyer-tapes, of a roller having milled or corrugated disks orsections of a larger diameter than the tape bearing or supportingsurfaees'of said roller, whereby the milled sections of the roller projeet beyond the tapes and havea fastersurface speed,

.substantially as and for the purpose set forth.

2. In a sheetfconveying attachment for paper-folding machines, thecombination,with a board or table having a system of conveyertapes andadapted to bridge the space between a folding-machine andprinting-press, of an upper tape-guiding roller having milled orcorrugated disks or sections of a larger diameter than the tape bearingor supporting surfaces of said roller, substantially as and for thepurpose herein set forth.

In testimony whereof I afix my signature in presence of two witnesses.
